Database Branching in Postgres: Git-Style Workflows with Databricks Lakebase

Database branching is a modern approach that addresses the limitations of traditional database management in development workflows. Unlike conventional database copies, which require significant time and resources to duplicate data and schema, database branching allows for the creation of isolated environments that share the same underlying storage. This method utilizes a copy-on-write mechanism, enabling branches to be created in seconds regardless of database size, with storage costs tied only to the changes made. Key features of database branching include: - Branch creation time: Seconds, constant regardless of database size. - Storage cost: Proportional to changes only, not the total data size. - Isolation: Each branch has its own Postgres connection string and compute endpoint. - Automatic scaling: Idle branches can scale compute to zero, incurring costs only when active. The architecture supporting this approach separates compute from storage, allowing multiple branches to reference the same data without conflict. This design facilitates time travel capabilities, enabling branches to be created from any point in the past for instant recovery and inspection. Database branching unlocks new workflows, such as: - One branch per developer, providing isolated environments for each engineer. - One branch per pull request, automating branch creation and deletion tied to PRs. - One branch per test run, provisioning fresh databases for each CI pipeline execution. - Instant recovery from any point in time within a designated restore window. - Ephemeral environments for AI agents, allowing programmatic database provisioning. Databricks Lakebase offers this database branching capability, transforming the database from a bottleneck into a streamlined component of the development process.

This fake Windows support website delivers password-stealing malware

A phishing campaign has been identified that uses a counterfeit Microsoft support website, microsoft-update[.]support, to trick users into downloading a malicious Windows update disguised as WindowsUpdate 1.0.0.msi. This file, created on April 4, 2026, appears legitimate but contains malware designed to steal sensitive information. The campaign targets French-speaking users, leveraging recent data breaches in France to create convincing scams. The malware, once executed, installs an Electron application that runs a Python interpreter, which then deploys various data theft tools. It employs two persistence mechanisms: modifying the Windows registry and creating a shortcut in the Startup folder. The malware connects to external sites for reconnaissance and data exfiltration, using domains like datawebsync-lvmv.onrender[.]com and store8.gofile[.]io. The malware's components have evaded detection by antivirus tools, with VirusTotal reporting zero detections for the main executable and its launcher. Users are advised to check their registry, remove suspicious files, change passwords, and run a full system scan if they suspect installation of the malicious update. Safe updating practices include using the built-in Windows update feature and being cautious of phishing attempts. Indicators of compromise include specific file hashes, domains associated with the phishing campaign, and file system artifacts related to the malware's installation.

PostgreSQL logical replication: How to replicate only the data that you need

Many organizations using PostgreSQL face challenges in replicating data across different logical databases while controlling shared information. PostgreSQL 15 introduces native logical replication with column-level and row-level filtering within publications, allowing precise control over data transfer between PostgreSQL databases. Logical replication operates on a publish-subscribe model, where the source database logs changes to the Write-Ahead Log (WAL) and applies publication filters to transmit only the relevant data to the target database. Two filtering modes are available: column-level filtering allows users to specify which columns to replicate, while row-level filtering uses WHERE clauses to determine which rows to include. Both filtering modes can be combined in a single publication. The SQL syntax for creating publications and subscriptions is consistent across various PostgreSQL environments, with specific configurations required for enabling logical replication. Use cases for logical replication include multi-tenant SaaS data isolation, regional data distribution for ecommerce, PCI DSS compliance in financial services, development and testing environments, and retail inventory management. Prerequisites for implementing logical replication include using PostgreSQL 15 or later, ensuring network connectivity, having a user with replication privileges, enabling logical replication on the source instance, and monitoring WAL retention. Logical replication has limitations, such as the need for a replica identity for UPDATE and DELETE operations, the non-replication of DDL changes and sequences, and potential performance overhead during initial synchronization and ongoing replication. After testing, it is advisable to clean up by removing replication resources to prevent unnecessary costs.

How to use and deploy Android Work Profile in your business

The mobile device has become a dual-purpose tool for personal and professional needs, enhancing productivity but also introducing security challenges for organizations with bring-your-own-device (BYOD) policies. Samsung addresses these challenges with its Android Work Profile feature, which separates business applications and data from personal content on devices like the Galaxy S26 Series, Galaxy Z Fold7, and Galaxy Z Flip7. Android Work Profile creates two isolated profiles on a single device, allowing IT teams to manage corporate applications while keeping personal information private. IT administrators can monitor work profile applications and data but cannot access personal profiles, ensuring employee privacy. Employees can easily switch between work and personal applications and activate a “pause work apps” feature during off-hours. To set up Android Work Profile, organizations need an Enterprise Mobility Management (EMM) solution and the Android Device Policy app. The Samsung Knox Suite provides tools for managing and securing devices, including Knox Mobile Enrollment and Knox Attestation. Android Work Profile benefits businesses by enhancing data security and reputation while promoting work-life balance for employees.

“We’ll keep making Warframe if there’s one player count,” Digital Extremes’ Megan Everett asserts. “I don’t care what SteamDB says”

The gaming industry has seen a shift in how success is measured, particularly focusing on initial player counts since the launch of games like Marathon and Highguard in 2026. Warframe, which launched in 2024 with a peak player count of 22,000, has grown to reach 175,546 players on PC after the release of The Old Peace in December 2025. Community director Megan Everett noted that the game has achieved new internal records despite not hitting its all-time high. Creative director Rebecca Ford humorously suggested a new release titled 'Player Count' to address the ongoing debate about player metrics. She highlighted the competitive landscape, noting that Warframe launched amidst 435 titles, compared to 20,014 games released in the same year today. Everett emphasized the importance of ongoing growth and player engagement over mere numbers, stating that a poor launch does not equate to a dead game. The success of The Old Peace was attributed to the introduction of content skips, which allowed players to bypass extensive story content. The team is committed to community engagement and innovation, with new characters and mechanics being introduced to keep the game fresh.

Is It Time for a New Laptop Battery? This Secret Windows Report Will Let You Know

Windows laptops allow users to generate a battery report through Windows PowerShell. To create the report, users must open Windows Terminal as an administrator and enter the command powercfg /batteryreport /output "C:battery-report.html". This command generates an HTML file named battery-report.html saved in the C: drive. The report includes information about the laptop's battery health, recent usage, battery usage over the last three days, usage history, battery capacity history, and battery life estimates. The report shows the design capacity and full charge capacity of the battery, along with a comparison of expected and actual battery life. For example, a laptop designed for 6 hours and 2 minutes of battery life may currently last only 4 hours and 52 minutes.
